What size copper wire is good for 150 amps?
| SERVICE ENTRANCE CONDUCTORS SIZE AND RATING | ||
|---|---|---|
| Service or Feeder Rating | Copper Conductors | Aluminum or Copper-Clad Aluminum |
| 125 Amps | #2 AWG | #1/0 AWG |
| 150 Amps | #1 AWG | #2/0 AWG |
| 200 Amps | #2/0 AWG | #4/0 AWG |
What size wire do I need to run 100 Amp Service 150 feet?
What is the right wire size for 100 Amp service 150 feet distance? You should get 2/0 AWG Copper wire or 4/0 AWG Aluminum wire for single-phase circuits. And, 1/0 AWG Copper wire or 3/0 AWG Aluminum wire if you have three-phase circuits. For these wires, the average voltage drop should be 3%.
What size copper wire should be used for a 100a 240v service?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
What amperage is #2 copper Good For?

| 3 | 120 | 165 |
| 4 | 105 | 140 |
How many amps can 4 gauge copper wire handle?
85 amps
How many amps can a 4 gauge wire handle? It has a rated ampacity of 85 amps at 75°C. This means that, for average use, the 4 gauge wire can handle up to 85 amps safely.
How many amps will #4 copper wire carry?
Wire Size and Amp Ratings
| Wire Size | 75°C (167°F) | |
|---|---|---|
| AWG | (mm²) | Copper |
| 6 | (13.3) | 65 |
| 4 | (21.2) | 85 |
| 3 | (26.7) | 100 |
What size wire do I need for a 150 amp service?
Looking at your 150 ampere service as an example (Excluding any temperature or other adjustments). Table 310.15 (B) (16) says that 1 AWG copper is good for 130 amperes at 75C. So if no adjustments were needed, 1 AWG would be allowed as service conductors for a 120/240 volts, 3-Wire, single-phase dwelling service.
What is the minimum AMP size for the Neutrals?
dana, 250.66 and 250.122 are just minimum sizes for the neutrals. You calculate the size in 220.61 and refer to the resi chart in this case. I have a 100A calculated load. I have a 100A calculated load. Click to expand… Remember you are sizing your full 195 amp load of this chart, using 2/0 hots.
What size neutral wire for 120/208 volt service conductor?
In a 120/240 volt system the load on the neutral conductor is reduced. No substantiation was provided to justify applying the Table to 120/208-volt service conductors. Click to expand… dana, 250.66 and 250.122 are just minimum sizes for the neutrals.
Can you use a number 4 neutral wire for a house?
Where does it state you cannot use this table unless all the wires are the same size. If the calculated load of the services is 100 amps and #4 is allowed why then wouldn’t a #4 neutral be allowed. You are always allowed to downsize the neutral if you can so I don’t see why 310.15 (B) (7) can’t be used for a residence.
